There is one other possibility that we, as investors, could consider. Mr. Buffett is getting older and it is possible that, following his death, the price of BRK-A will materially decline. Traditionally, Berkshire has bought back its stock whenever its price got close "enough" to its book value. I fully expect this to happen again when Mr. Buffett passes away. The current price to book value ratio is 1.65. I would be hard pressed to purchase the stock at $500k per share (a 33% reduction from its current price) but, if one could emotionally ignore the price, the logic of the purchase would be the opportunity of a lifetime.
